I have a Tmobile z10 and I had successfully been syncing icloud on my calendar through the caldav server.

But this weekend it stopped. I am running BB OS 10.0.10.85. Not sure if there was an update that caused this to stop working.

Now when I tried to re-install the calendar account on the z10, it tells me it cannot authenticate my account, although I know the password I am using is correct, as I have confirmed it by logging into my icloud account on my laptop.

Very frustrating, as I stuck with BB over the new Iphone at t-mobile based on the ability to sync with icloud. My contacts are still syncing, as far as I know.

in fact, it shouldbe a problemofauthentication, and thensomething about a ssl certificate...I havealso tried toenterdifferentdoors afterthe server address:caldav.icloud.comadding :443and other ...the problemremains the same...

I alsothought it wouldbe aspite from apple againstbb,since the problemaffixes,essentially,those like me whohave gone fromIPto BB...

I don't think ssl is the issue. I have posted in here because I have issues with caldav too. I don't use I cloud but a personal drive with a caldav application on it. It doesn't have ssl though I can enable it and I have tried both ssl and non ssl. Before I updated to 10.1, I could add my my caldav server but it never worked on my z10. But now I cannot even add it to my phone, it fails to authenticate. But all my other devices work and authenticate fine with the same settings. Sunbird, iPhone, etc. It is definitely a big issue with the blackberry OS. I'd love to see some acknowledgement from the rim team, this would at least give us some hope and reassure us, even if it is all b.s. Numerous tweets, emails, etc nothing. Unacceptable in my opinion. The only way is for us to bombard RIM until they listen. Tweet them, email them, they need to be made aware that this isn't an isolated case.

There is other solution - full refund and purchase other device. I remember 3 days BIS outage.
